Have the Nifty ordered me looking for my new Mini Drive Mach Book Air for something, because I realized with horror that my plan to use an ordinary SD card or microSD with adapter but was a bit stupid (Normal SD card is halfway through). Everyone who plans his Macbook with a SD card to expand is not really about the Nifty herrum Of course there are other vendors (but these are color and material technology not as high as the Nifty) Basically, the Mini Drive drops after plugging into the Macbook no longer on. You may be stuck in the Book safely transport bag without fear of having to be the lynch during transport the card reader.
